Thanks again for all the suggestions. Was able to locate and purchase a nice leather IWB holster for the 3913. I know, it's only a holster (no big deal we buy holsters and equipment all the time). I contacted four holster manufacturers inquiring if they stock or could make a holster for the discontinued 3913. Of the four only one responded: Muddy River Tactical. Kevin at Muddy River Tactical contacted me in less than 24 hours advising he could supply one. I ordered right after Kevin emailed me (last Monday) and received the holster yesterday (Saturday). BTW, not one of the other three manufacturers responded back as of today. I realize some of the big name holster manufacturers are busy and don't want to bother with a discontinued model (especially when there are millions of Glocks, SIG's, etc out there). Muddy River Tactical products are a family business and all products are made in the USA. For the record, I have no personal/business connection with MRT (and not compensated in any manner). Just wanted to share with the forum a positive firearm related buying experience. Obligatory pics attached.
